Dams and reservoirs

Dams are large structures built across rivers or streams to block water flow, creating a reservoir—an artificial lake—behind them. These reservoirs store water for various uses, including drinking, irrigation, hydroelectric power, and flood control. Dams regulate water flow, prevent floods, and generate electricity through turbines. They also support recreation and wildlife habitats. Properly designed and maintained dams are crucial for managing water resources sustainably and safely, while their environmental and social impacts require careful consideration.
